Koneksi Scan Barcode Dengan Php Mysql
I am trying to set up a library for books in my work place. I have the MySQL database set up, with the data and everything. Now what i am trying to do is have the ability for someone to take their phone, scan a QR code for a certain book, and it would check out the book. I have a field in the database that states if the book was checked out, and another stating check out date. How would i access my database externally through the internet and QR codes, and have the QR code change data in specific fields of my database, thanks. I used phpMyAdmin to set up the database, and my webhost is iPage.com.

As I already noted in a comment you question is simplar to the question Tranfer QR Code Into a MySql Database. But in your question are more points unclear: So far I did some research some guy from the support of iPage.com told me that php is supported by your webhoster in all packages.
So I will give your some hints how you can implement that with php:
For the database access use prepared statements and PDO. Here is a good tutorial about PDO.
For clean and simple urls for some kind of REST API use mod_rewrite with .htaccess:
Basically you have to check if mod rewrite is enabled. In your case you can skip this, but in general you have to check if you have a AllowOverride All statment in your directory directive.
Just put this code in your .htaccess file:
So you can access the qr code in yourphpfile.php with this simple variable access:
For the scanning part you can use the ZXing Barcode Scanner app:
If the user has the ZXing installed the brower will open the app automatically. If not the user will get a simple site which gives him or her a hint how to install the app.
You just have to link to the page the resulting value of the qr code will be submitted to the url http://example.com/seachbook/QR-code-content.
See also the full explanation on the ZXing documentation.
Membuat Barcode Dengan Php
In general that certainly is possible. Actually every QRCode / barcode stores information. But usually the size of that information is pretty small. Typically only references like URLs or numbers (IDs) are stored and the 'real' data is retrieved from a database using those references. But strictly speaking that is a form of storing information in a QRCode / barcode.
Looking closely we see that the data is stored in the code itself, not inside a database if we are talking about that small amount of data. Certainly that data can be stored inside a database when the code is read, all you need is a trivial piece of software. But that makes little sense in most cases, since the data already is stored. If you want to use a database to combine data from different sources, so if you only want to use codes as a means of transport, then reading the codes is just a replacement for typing the information in with a keyboard. So no magic here, nothing code specific you have to consider.
here is the php script to generate QR directly in db
